GAK submersible sewage pump automatic coupling system advantages: 1. After using the automatic coupling device, easy installation and maintenance. Fixed installation in case of no automatic coupling device, in case of pump failure sewer maintenance personnel need to unscrew the screw, lifting water pump repair, or other small water pump smoked went down for maintenance, if the water is dirty, people very hard to get in, then overhaul encountered great difficulties. But after the installation of the automatic coupling device GAK submersible sewage pumps needed lifting, people may not need to unscrew the screw into the water, the pump can directly improve after the completion of repair can be achieved along the rail down the pump and pipe sealing, thus the pump running. Small sewage pump can be freely installed, a large sewage pumps are generally equipped with automatic coupling device can be automatically installed, installation and maintenance very easy. 2. GAK compact submersible sewage pump automatic coupling device structure, small footprint. Due to sneak under the liquid sewage pump work, it can be directly installed in the sewage tanks, without the construction of specialized pumps and pumping stations to install machine, you can save a lot of land and infrastructure costs. GAK composition submersible sewage pump automatic coupling device: automatic coupling device GAK submersible sewage pumps, including couplers, coupling flange, guide rod, the fixed plate, coupling the base of the contact surface of the coupling slide open with an annular recess slot tightly fixed on a soft gasket groove. Coupled contact surface with the above structure, the coupling and coupling slide base is firmly sealed annular sealing groove. GAK submersible sewage pump automatic coupling device is generally based on the use of different environments, I developed a cast iron submersible sewage pump automatic coupling device and stainless steel submersible sewage pump automatic coupling device. Automatic coupling device can also be set made of welded rail, no seam steel pipe, stainless steel tube. To use the chain guide can also be customized stainless steel chain and chain guide guidance when lifting. At present, I cast automatic coupling device configuration are the following: automatic coupling device GAK50 submersible sewage pump (cast iron) GAK65 submersible sewage pump automatic coupling device (cast iron) GAK80 submersible sewage pump automatic coupling device (cast iron) automatic coupling device GAK100 submersible sewage pump (cast iron) GAK150 submersible sewage pump automatic coupling device (cast iron) GAK200 submersible sewage pump automatic coupling device (cast iron) GAK250 submersible sewage pump automatic coupling device (cast iron) GAK300 type Automatic submersible sewage pump coupling device (cast iron) GAK350 submersible sewage pump automatic coupling device (cast iron) GAK400 submersible sewage pump automatic coupling device (cast iron) GAK450 submersible sewage pump automatic coupling device (cast iron) GAK500 submersible sewage Automatic pump coupling device (cast iron) GAK600 submersible sewage pump automatic coupling device (cast iron) Currently my company with stainless steel automatic coupling device are the following: automatic coupling device GAK50 submersible sewage pump (stainless steel) GAK65 submersible sewage Automatic pump coupling device (stainless steel) GAK80 submersible sewage pump automatic coupling device (stainless steel) GAK100 submersible sewage pump automatic coupling device (stainless steel) GAK150 submersible sewage pump automatic coupling device (stainless steel) as long as the customer in accordance with submersible sewage pump water can support the same caliber caliber automatic coupling device, general sewage pump water caliber GB 6 kg flange. Automatic coupling device GAK GAK automatic coupling device automatic coupling device Overview of a submersible pump outlet flange and outlet road automatic docking system by water submersible pump flanges, additional coupling flange and outlet flange seat imported composition, location near a pair of wedge and wedge-point level of the card in the center line on both sides of the flange inlet flange and outlet flange coupling additional seat each. When the submersible pump from the top landing puddles, additional coupling flange and outlet sides of the wedge card holder inlet flange on both sides of the wedge card on the card together under the weight of submersible pumps and wedges card ramps, Two flange tightly affixed together, like two sides of the flange with two bolts tight, like hydraulic submersible pump is bigger and can not open a lot of leaking flange. When the submersible pump lift up from puddles, two pairs of wedges card can be easily disengaged along the slope, in order to achieve functional automatic coupling device. It can be easily attached and detached while the submersible pump automatically solve a lot of leaking flange coupling between the two issues, thus saving energy.
